I UNITED STATES "PATENT WILLIAM MASTERS, OF KANSAS CITY, MISSOURI.

OIL-HEATER.

SPECIFICATION forming part of Letters Patent No. 513,404, dated January23,1894.

i Application filed February 1, 1893. Serial No. 460,540. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM MASTERS, of Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Oil-Heaters, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to certain new and useful improvements in oil orgas heaters; and my invention consists in certain features of noveltyhereinafter described and pointed out in the claim.

Figure 1, represents a vertical, longitudinal section of my improvedstove. Fig. II, is a top view of the top plate. Fig. III, repre- Fig.IV, represents a bottom view of the heat and flame deflector. Fig. V,represents a crab or spider which is placed over the central flue at thetop of the stove.

Referring to the drawings: 1, represents the base supported by legs 2,said base being provided with lugs 3, for supporting the reservoir 4,having the usual Argand or Rochester burner 5.

6, represents the base plate hinged to the base as shown at 7; and 8,represents the ordinary fender. l i i 9, represents a series of verticaltubes extending from the base plate 6, to the top plate 10, passingthrough each of said plates; thus forming a passage-way for: the freshair from the outside through the bottom chamber 11, of the base throughthe drum 12, in which said tubes are located, said top and bottom plates6 and 10, forming the top and bottom of said drum. The air, after beingheated in its passage through the tubes 9, passing out through apertures13, in the cap or cover 14.

15, represents a hollow head having arms 15 extending between thevertical tubes, a chamber 16, and a cone shaped downward extension 17.The head 15, is supported within the drum 12, a short distance above theburner 5, with the cone shaped extension 17, located directly over thecenter of the burner; said cone shaped extension forming a deflector fordeflecting the flame and heat which pass upward from the burner. Thehead 15 and chamber 16, are connected with the chamber 11, in the baseby means of a series of short supporting tubes 18 alternating with thevertical tubes beneath the arms of the head, by which means air may beadmitted from the chamber 11, through the tubes 18, into the chamber16,where it is heated and passes out through a central vertical tube 19,connected with the head 15, said tube extending nearly to the top 10, ofthe drum; but leaving asufficient space surrounding its uppper end forthe free escape of the heated air and for the com mingling of the mixedair from the burner and from the chamber ll,the heated air from theburner passing up through an annular space 20, outside of the tubes 9,and between said tubes, thus heating the air within the tubesand at thesame time heating the walls of the drum, giving a large radiatingsurface, a portion of the heated air passing out through a centralaperture 21, in the top plate, and a portion through openings 22, insaid plate.

By the construction shown the heated airis contracted in the passage-wayfrom the central chamber 16, out through the central tube 19. It will beobserved that in this device the main body of the heated air isdischarged in compactform throughthe central tube so as to bring thestrongest heat to bear upon any article placed on the support 25, thetube 19, being of less diameter than the chamber 16. As the heated airpasses up through the tube 19, it being hotter than the surrounding air,the tube 19 acts as an injector by drawing the surrounding air throughthe annular space around the upper end of the tube. Therefore,practically, all the heated air is passed up through the central openingin the top of the drum; so that by placing any article over the same itwill be heated very rapidly.

- 23, represents an annular flange on the top of theplate 10, whichcomes in contact with the inner side of the drum, and holds the topplate in position.

24, represents an annular flange fitting down on the inner side of thetubes 9.

25, represents a crab which rests on the top plate 10, over the centralaperture 21; and 26, representslugs extendingup onalevel with the t-icaltubes, a heating chamber, and a central vertical tube extending to apoint adjacent to the central opening, and short vertical air tubesalternating with the Vertical air tubes r 5 beneath the arms of thehead; substantially as described.
